The closest star system to the Earth is the famous Alpha Centauri group. Located in the constellation of Centaurus (The Centaur), at a distance of 4.3 light-years, this system is made up of the binary formed by the stars Alpha Centauri A and Alpha Centauri B, plus the faint red dwarf Alpha Centauri C, also known as Proxima Centauri.

The Sun replaced with other Stars

This visualization shows how the sunset could look like to a human observer if our Sun was replaced by some of the other stars in our galaxy with different sizes and magnitudes, namely Barnard’s Star, Gliese 581, Tau Ceti, Kepler-23, Alpha Centauri A, Procyon, Sirius, Pollux, Arcturus and Aldebaran.

It is just a concept, as liquid water and the Earth as we know it could not exist in the vicinity of the most stars in this graphic. Visualizations are based on the absolute brightness, spectral class and the radius of each star.

RIP Anton Yelchin (1989-2016) - The great young actor best known for portraying Chekov in the current version of Star Trek (2009/2013/2016) died today at age 27 on a strange car accident. Born in Leningrado, Soviet Union, Yelchin’s career started in 2000, on several minor projects until he got noticed by Scott Hicks who cast him alongisde Anthony Hopkins in Stephen King’s adaptation Hearts in Atlantis (2001). From there, he appeared in more than 60 projects between films and TV shows such House of D (2004), Huff (2004-2006), Fierce People (2005), Alpha Dog (2006), Charlie Bartlett (2007), New York, I Love You (2008), Terminator Salvation (2009), Memoirs of a Teenage Amnesiac (2010), Like Crazy (2011), The Beaver (2011), You and I (2011), Fright Night (2011), Odd Thomas (2013), Only Lovers Left Alive (2013), Dying of the Light (2014), Experimenter (2015), and with five upcoming (already completed) projects, including the 3rd Star Trek installment. A brilliant, funny, and talented man that leaves us so soon and I’m gonna miss him so much.

Even The Stars is a space exploration game with no objectives, quests or story-lines.  You simply wander through space without a purpose, exploring alien planets, discovering strange landmarks, getting lost, getting old and eventually passing away.

You control the movement of your ship with the mouse and keyboard but other actions require you to type commands, such as ‘warp’ or ‘disembark’.  When you come across an interesting landmark on a planet (from fun-fairs to Monoliths), you can explore or ‘stay’, allowing you to write a short log about your journey and making you grow a little older.  You’ll eventually die of old age and be treated to picture of the universe, with your last route mapped out, accompanied with your logs describing your voyage.

It’s a short, sweet and simple game that encourages exploration for explorations sake.  In Even the Stars there’s no levelling up, high scores or objectives, simply the joy of discovering weird stuff in space, writing about it and building your own story – Space Blogging.

Stephen Hawking Is Building Thousands Of Tiny Spaceships To Find Intelligent Life
When asked what extraterrestrial intelligent life might look like, Hawking answered, "Judging from the election campaign, definitely not like us."
By Ema O'Connor

World famous theoretical physicist Stephen Hawking and Russian billionaire Yuri Milner announced Tuesday their newest attempt to find extraterrestrial life: a project called Breakthrough Starshot.

“Today we commit to the next great leap in the cosmos,” Hawking told reporters at the top of the World Trade Center in New York City. “Because we are human and our nature is to fly.”

Hawking said the goal of Breakthrough Starshot was to reach Alpha Centauri, the closest star system to us, within a generation by using thousands of tiny spaceships.

Astronomers believe an Earth-like planet could exist within the “habitable zones” of Alpha Centauri, located 25 trillion miles away. It is therefore the most likely place to find life or even, as Hawking said, a possible new home for future humans.

Breakthrough Starshot’s spacecrafts, which they call “nanocrafts,” will be a gram-scale computer chip that will include “cameras, photon thrusters, power supply, navigation and communication equipment,” Avi Loeb, a Harvard scientist involved in the operation told reporters.

A rocket would deliver a “mother ship” carrying a thousand or so of the nanocrafts into space. Once in orbit, the crafts would be propelled with thin sails and hyper-powerful laser beams shot from Earth into the universe to explore and discover. There the crafts would take pictures of their surroundings, which would take around four years to be sent back to earth.

The nanocrafts would travel at around 20% of the speed of light, Loeb said. At that rate it would be possible to reach Alpha Centauri in around 20 years, and the potentially habitable planets within 70. Using the best currently existing technology, it would take some 78,000 years.

The impact of a coronal mass ejection on New Year’s eve brought a celebration of sky lights to planet Earth’s high latitudes yesterday. In this New Year’s nightscape, the shimmering reddish curtains of aurora australis along a southern horizon are captured over Morgiana, SW Victoria, Australia. Of course, more permanent jewels of the southern skies are on the scene. The southern Milky Way, Alpha and Beta Centauri, and bright stars of the Southern Cross are on the left. In silhouette, branches of the large foreground tree stretch across the Milky Way’s satellite galaxies, the Large and Small Magellanic clouds. The bright star framed near the tips of tree branches at right is Achernar. Alpha star of the constellation Eridanus, Achernar is sometimes known as the southern end of the river.
